3) Frequency characteristics. Frequency characteristics are often determined by the dielectric of the capacitor. That is to say, no matter whose product is the same ceramic medium, the frequency characteristics of the capacitor are the same. The choice of Italy materials.

1) Current capacity. When the over current is large, the life of the capacitor is long.

The second reason is: the overcurrent caused by the separation harmonics of the power networkHarmonic current is also one of the biggest "killers" causing damage to high-voltage capacitors. In the daily operation process, when the harmonic current flows into the capacitor, it will be superimposed on

Reason one: operating voltage is too highI believe many engineers are aware that the high voltage capacitor operating voltage can reflect the substation bus system voltage, and directly affect the capacitor life and function. The active power loss in the operation of high voltage capacitor is mainly
